The 2024 United States Senate election in Texas was held on November 5, 2024, to elect a member of the United States Senate to represent the state of Texas. Republican incumbent Ted Cruz won re-election to a third term, defeating Democratic challenger and U.S. Representative Colin Allred. The primary election took place on March 5, 2024, during Super Tuesday.
Original polling showed Cruz as a clear favorite, but polls closer to the election showed a closer race. Cruz ultimately outperformed polling and expectations and won re-election by 8.49 points, improving on his 2018 margin by six points and flipping thirteen counties. Allred did outperform Kamala Harris in the concurrent 2024 U.S. presidential election in Texas by 5 points. With slightly over 53% of the vote, Cruz received the lowest vote share for any incumbent Republican senator in the 2024 election cycle. Likewise, Allred received the highest vote share for a Democratic candidate in a seat occupied by a Republican (only Dan Osborn, an Independent running in Nebraska, received a larger vote share for a challenger in a Republican held seat).
Cruz won Hispanic and Latino voters, particularly those living on the border with Mexico who had traditionally supported Democratic candidates; exit polls showed 52% of Latinos supported Cruz, a 17-point increase from 2018. Cruz received the most raw votes for a U.S. Senate candidate in Texas history, a record previously achieved by John Cornyn in 2020.

## Background

Texas is generally considered to be a Republican stronghold, having not elected a Democrat to any statewide office since 1994. Republicans control both U.S. Senate seats, all statewide offices, both houses of the Texas Legislature, and a large majority in Texas's U.S. House congressional delegation. Cruz was first elected in 2012, defeating Paul Sadler by 15.84 points and was reelected in 2018 by only 2.56 points, narrowly defeating Beto O'Rourke. The close elections in 2018 prompted many electoral analysts to speculate that Texas could become a swing state, but in the 2020 and 2022 elections, Republicans increased their margins of victory. This race was considered to generally favor Cruz, but some considered the race to have the potential to become competitive.
